From d05fa0d94959e354c6f028826bc540787791d6af Mon Sep 17 00:00:00 2001 From: Kyle Evans Date: Thu, 27 Jun 2019 14:03:32 +0000 Subject: bectl(8): create non-recursive boot environments bectl advertises that it has the ability to create recursive and non-recursive boot environments. This patch implements that functionality using the be_create_depth API provided by libbe. With this patch, bectl now works as bectl(8) describes in regards to creating recursive/non-recursive boot environments.
